SD45 2 Speed "Supa" Anchor Auger Drive - Digga

📘 Overview

The Digga SD45 is a 2-speed Supa anchor drive for excavators 15-30T class — delivering 30,000-45,000 ft-lbs of torque for helical screw anchor applications. Built with Digga's compact high-quality gearbox, built-in PRV (pressure relief valve), ECV (energy control valve) to prevent rapid decompression from pile kickback, and engineered hood and ears for maximum strength. Extreme duty shaft locking system. No complex hoses, valving, or filtration. Made in Dyersville, Iowa, USA.

⚙️ Key Features

• Model SD45 | 30,000-45,000 ft-lbs | For excavators 15-30T class
• 2-speed Supa anchor drive
• Compact Digga-made gearbox with built-in PRV
• ECV (energy control valve) — prevents rapid oil decompression from pile kickback
• Engineered hood and ears for maximum strength
• Extreme duty shaft locking system
• No complex hoses, valving, or filtration required
• Made in Dyersville, Iowa, USA

🔑 Benefits

• Built-in ECV prevents dangerous rapid oil decompression during pile kickback — the primary failure mode on high-torque anchor drives — when a helical pile encounters an obstruction and stops suddenly under high torque, the stored rotational energy in the machine's hydraulic system releases rapidly. Without ECV, this creates a pressure spike that can damage the drive, the hose circuit, and potentially cause machine instability. The ECV controls this energy release safely.
• Digga-designed gearbox rated specifically for {app_desc} loads — not a drilling drive modified for anchoring — anchoring creates cyclical torque spikes fundamentally different from drilling's steady resistance. The Supa/HP drive gearbox is engineered for anchor load profiles, not adapted from a drilling drive.
• Extreme duty shaft locking handles the high torque and pull-out forces of pile installation
• Simplified hydraulic circuit reduces installation time and failure points
